Patented Jan. 19, 1915.

Application filed June 1, 1914. Serial No. 842,246.

To all whom it may com-em Be it known that I, CnnsrnaA. HEIN- znmrax, acitizen of the United States, residing at the city of Belleville, countyof St. Clair, and State of Illinois, have invented a certain new anduseful Improvement in Roller-Bearings, of which the following is a full,clear, and exact description, such as will enable others skilled. in theart to-which' it appertains to make and use the same.

This invention relates to roller bearings, and has for its main objectto provide an inexpensive and serviceable bearing in 'which the cage canbe stamped from sheet metal, and which is so constructed that therollers will not drop out of same when the cage is removed, from thecone or inner member of the bearing.

Anotherobject is to provide a rollerbearing in which novel means areemployed to retain the cage in position in the bearing.

Other objects and desirable features will be hereinafter pointed out.

Figure 1 of the drawings is a vertical sectional view of a rollerbearing constructed in accordance with my invention. Fig. 2 an end viewof the cage and the inner bearing member. Fig. 3 is a verticallongitudinal sectional view of the cage showing one of the rollersarranged in opshaped and the outer member consisting of pered slightly.

a cup ,or ring whose inner. surface is ta The rollers are held in acertain position with relation to each other by means of a cage which.consists of a tapered cylindrical-shaped member 1, preferably stampedfrom sheet metal, and provided with openings 2 for receiving the rollersC. 'Outward movement of the rollers with relation to-the cage 1 isprevented by the side edges of the openings 2 in said cage that receivesaid rollers, which. side edges are beveled or curved slightly, asshown'in Fig. 4, so as to conform approximately to the shape of therollers. Inward movement of the rollers is prevented by means of anannular flange 3 at one end of the cage, which cooperates withprojections t on the rollers, and fingers 5 that project inwardly fromthe inner side of the cage and partially surround the rollers G,'as,

shown clearly in Figs. 3 and l. The annular flange 3 is formed integralwith a ringshaped flange- (3 arranged at one end of the cage 1, and thefingers 5 are arranged in pairs. and are long enough so that they willextend past the centers of the rollers.

In the embodiment of my invention herein shown the fingers 5 areintegral with the body portion 1 of the cage and are formed by leavinguncut strips of metal in the (ipeuings when said openings are formed,

as shown clearly in Fig. 5, these strips'bcing thereafter bent inwardlyso as to conform approximately to the shape of 'the rollers C, as shownin Fig. 4.

A. pair of fingers 5 is preferably provided for. each of the rollers C,said fingers being adapted to lie on opposite sides of the rollers Gsoas to partially embrace the same. As shown in Figs. 3 and 5, the twofingers 5 that comprise each pair are staggered or oil'set with relationto each other in order that they may be made of suilicient length, fromthe available metal between the sides of the openings 2, to extend farenoughbeyondthe center of the rollers C to prevent inward movementthereof llv forming. the strips or fingers in the n'ianner just abovedescribed I am enabled to provide a roller-retaining means in the pagethat is very ethcient and simple. and

which can be formed at the same time-the cage is being formed -at a veryslight additional cost. The spring lingers 5 and the flange 3 absolutelyprevent the rollers C from dropping out of. the openings :2 when thecage is being placed in or removed from operative position in thebearing, and said fingers can be shifted or sprung slightly to permit ofthe removal of a damaged roller and the insertion of a new one. Thefront end face 6 and the flange 3', besides forming a retaining meansfor the projections 4 on the front ends of the rollers, actas areinforcement at this end of the cage. and the rear end of the cage isstrengthened and reinforced by means of an annular flange 7 that is bentinwardly from the body portion 1 of the" cage.

From the foregoing it will be seen that I have provided a cage forroller bear-in that can be made from sheet metalthat 1s reinforcedat-its ends in a novel manner, so as to obtain the desired strength, andwhich is rovided with novel means for retainin t e rollers inoperativeposition.

Wit a ca eofthe construction heretofore p, described w er'einthe rollersare assembled inthe cage before it is placed in position in of inwar thehearing, it is necessary to provide a detachable abutment or retainingring on one end of theinner bearing or cone A that can be arranged inposition after the ,c'age'has been-placed on the cone A. As shown inFig. 1, the cone or bearin A is provided with an annular groove 8 ajacent the small end thereof, and after the cage has been placed inposition, a ring D is forced-or sprung'into said groove so that itformsnn revents the one annular abutment that and rollers from beingetached from bearing. In the embodiment of my invention herein shown thering D comprises a solid pew-i 'heralportion 9 ends. plurality (l lyextending angularly used spring fingers 10 that will yield or be orcedoutwardly toward the periphery of the ring when said ring'is beinforced-over the small end of the cone A, and which will sprin inwardlyas soon as the groove 8 is reac ed, and thus securely hold the ring inoperative position in said groove, as shown in Fig. l. A roller bearingof the construction above described is very light,'simple inconstruction, highly efficient and can be produced at a low cost ofmanufacture.

Having thus described my invention, what 'I claim is:

1. in a roller bearing, a cylindrical sheet metal cage provided with ,aplurality ofroller-receiving openings, rollers arranged in saidopenings, said rollers being of greater diameter than the width of saidopenings, and fingers curved inwardly from the side edges of saidopenings and extending around opposite sides of said rollers toa pointbe -yond the center thereof, the fingers on one side of said rollersbein' staggered with relation to the fingers'on t e opposite side.

2. In a roller bearing, a cage, rollers perin, a cone on which saidrollers inanently arranged inmid'cage, a com on as which said rollersbear, said cone being provrded with a groove ad'a/cent one end thereof,and a ring provide with a plurality of inwardly disposed springfingersthat are formed in said cone adjacent one end thereof.

4. In a roller bearing, a cylindrical'ta I' pere'd sheet metal cageprovided with a plu rality of rollers permanently arr ed therear, and

means for ,prevcnting longitudinal movement or said rollers with r ectto said cone, said means comprising a at ring having a solid peripheralportion, and a plurality of angularly disposed fingers; lying" in thesame vertical plane and exten m-- wardly from said solid portion andwich cotiperate with an annular groove arranged ad acent one end of saidcone.

5. In a roller bearing, a tapered cylindri ,cal sheet metal cageprovided with a In rality of rollerreceiving openings, r0 lers arrangedin said'o enings, projections on one end of said rol ers that cooperatewith an annular pocket formed in said cage, a plurality of fingersintegral with said cage;

that artially embrace said rollers, a-cone on w ich said rollers bear,and means for tudinally of said cone, said means eomprising a. ringprovided with aymutilated portion that is adapted to be snapped intg agroove formed in said cone adjacent one end thereof. V

In testimony whereof I. hereunto afiix my 951 preventing said rollersfrom moving longisignature in the presence of two witnesses,
